Wood houses come in various structural types, mainly including the following categories:

1. Beam-column structure system: It is the most traditional structure, composed of large-span beams and columns capable of bearing vertical and horizontal loads. Beams, columns and purlins are generally made of solid wood or glued laminated timber, while floor and roof decks adopt wood-based structural panels. In early times, tenon-and-mortise joints were widely used for connection, and metal fasteners are commonly applied nowadays.

2. Light wood frame structure system: Popularly adopted in residential buildings in North America, it is assembled with standard dimension lumber, featuring light weight and cost efficiency, suitable for religious buildings, residences, industrial buildings and other constructions. Framed with 2×4 and 2×6 dimension lumbers, the walls and roofs are covered with OSB and plywood, ideal for single-family villas and low-rise apartments.

3. American SIPs structure: A high-performance wall panel composed of oriented strand board bonded with expanded polystyrene or polyurethane foam core, which integrates load-bearing and thermal insulation functions. Panels in different thicknesses meet diverse heat preservation and load-bearing requirements, and can be externally and internally fitted with solid wood cladding, cement fiber siding or gypsum board.

4. Log cabin structure: A characteristic dwelling style originated from Russian ethnic settlements, well-known for warm winters, cool summers and outstanding durability. Built by ax-hewn logs stacked layer by layer with stone and cement reinforced foundations, it is mostly fixed by wooden wedges instead of iron nails. Moss padding ensures great heat preservation while entrance porches effectively block wind. The buildings can retain natural log color or be painted in preferred hues, covering solid log structure, square timber structure and D-shaped log structure.
